SPECIFICATION forming part of Letters Patent No. 368,446, dated August 16, 1887.

Application liled April27, 1887. Serial No. 236.344. (No model.)

T all whom it may concern,.-

Be it known that 1 CYRUs W. BALDWIN, a citizen of the United States, residing at Yonkers, Westchester county, N ew York, have invented certain new and useful Improvements in Governors, of which the following is a specication.

The present invention relates to devices for governing or regulating the speed of engines,

1o motors, or other devices; and it consists in a novel governor automatically operated by an engine or motor for controlling a throttle or induction valve, or other regulating device.

In the drawings, Figure 1 is a side elevai5 tion of so much of a gas-engine as will illustrate an application of the improved governor. Fig. 2 is a plan view thereof. Fig. 3 is an enlarged central vertical section of a portion of the engine-cylinder, a valve, and a regulator 2o adapted to be controlled by the improved governor. Fig. 4 is an enlarged elevation of the governor. Fig. 5 is a central vertical section ofthe same, taken on the lined. Fig. 6 is a plan view of the end of t'ne regulating-rod, and

Fig. 7 is a sectional detail taken on the line e of Fig. 4.

In an application filed by me in the United States Patent Office August 19, 1886, No. 211,299, I have set forth and illustrated a 3o speed-regulating device for engines, consisting of a pair of parallel disks driven by the engine, a third disk arranged between said parallel disks and connected so as to operate an engine-valve and a governor-a ballgovernor,

3 5 as shown-operating to cause one or the other of the parallel disks to be brought into frictional contact with said third disk, according as the speed of the engine increases or decreases.

It is sometimes desirable to employ with highspeed engines a more compact structure than the use of a ball-governor permits, and to employ a governor whose action is more sensitive.

As shown in said drawings, Figs. 1 and 2, A represents the bed of an engineJ--a gasengine is illustratedmsupporting at one end the cylinder B,at the other the pillow-blocks, in which turns the crank-shaft O, carrying a 5o iiy-wheel,15, the crank being connected by a rod, 2, with the piston-rod, as is usual.

The improved governor G is contained by a flanged casting, 69, secured to the crankshaft or carried by or secured to the fly-wheel 15. Vithin the flange 70 of this casting are pivoted at 71 71 two levers, 72 72, each carrying a heavy weight, 73, which tends to iiy outward with the levers by centrifugal force when the iiy-wheel rotates, anda strong spring, 74, connected to the outer end of each lever andthe opposite lever near the pivoted end thereof, tends to draw the levers inward, and a set-screw, 75, on each weight is set to limit, by abutting against said flange 70,the outward movement thereof.

Upon the shaft C turns a ring, K, having a peripheral groove, o, to receive swivelinglugs 76 76, extending from opposite sides of a yoke, L, suspended from a rocking pin, 77, passing through a rock-rod, 78, supported by one of the pillow-blocks 79. The ring K has slots w, (shown in dotted lines, Fig. 4, and in Fig. 7,) into which extends lugs 80 on the hub of the wheel or the casting 69, and the ends of the slots and lugs are beveled, so that a very slight turning ofthe ring will bring the beveled faces together and thus cause the ring to.

move outward, carrying with it the yoke L. A spring, 8l, Fig. 5, between the yoke and the pillow-block, forces the yoke and ring inward to keep the beveled faces in contact soon as the ring is turned. The turning of the ring is effected by the action of the weighted levers, which are connected by rods 82 with lugs on the ring.

The face of the recess o is eccentric to the shaft C, as shown by dotted lines, Fig. 4, so that the yoke L is vibrated with its supporting rocking rod 78 as the ring K is turned by the movement of the Weighted levers, and the lower end ofthe yoke terminates in a fork, the two prongs 83 84 of which project past and upon opposite sides of a rod, 7c. The end of this rod 7c is formed into steps or provided with shoulders a, receding in opposite directions, as best shown in Fig. 6.

Vhen the parts are in the position shown in Fig. 4, the vibration of the yoke in the direction of the arrow 3 4 will have no eifect on the rod 7c; but when on the outward or inward motion of the weighted levers the ring K is turned and the yoke L is swung in the direction of the arrow 2, Fig. 5, the prong 83 will laterally, and a rod adapted to be moved by catch on one of the shoulders u, and as the the yoke, substantially as described. yoke then swings in thedirection of the arrow 2. rlhe combination, with weighted levers. 3 it will carry with it the rod k, and if the supported and carried by a revolving shaft 70 5 weighted levers continue to iiy out the yoke and operated by centrifugal force, of a vibratwill move farther in the direction of the arrow ing and laterally-moving yoke, cams operated 2 and the prong 83 will catch on the next by said levers for moving said yoke laterally, shoulder and feed the rod k farther backward. fingers projecting from the yoke, and a rod If, however, the weighted levers do not conadapted to be engaged and moved by said iin- 10 tin'ue to move outward, the yoke will simply gers, substantially as described.
